I use the following hacky script (which requires mencoder) to convert
HD videos so they can be displayed using the PVR-350 hw decoder. I am
pretty sure it should work for MediaMVP as well.
The script assumes that the input video has 16:9 aspect ratio and the
resulting file is 720x480 with the original video letterboxed to be
displayed on 4:3 TV.
if mencoder -o /dev/null $INFILE 2>/dev/null | egrep -q 'fps:(59|60)'; then
mencoder -of mpeg -mpegopts format=mpeg2:vbitrate=4000 -oac lavc -ovc lavc -lavcopts vcodec=mpeg2video:vbitrate=4000:keyint=18:aspect=4/3:acodec=mp2:abitrate=256 -vf $FILTER -fps $FPS -ofps $OFPS -vc mpeg12 -o $OUTFILE $INFILE
